Narrative:
Aborted takeoff after both engines would not produce power selected on constant takeoff torque. Taxied off runway 25 and stopped on taxiway to evaluate pertinent switch position and notify maintenance control by radio. Under supervision of maintenance control, I recycled electrical power to aircraft and tested constant takeoff torque (statically) on taxiway with a reduced power setting (reduced because full takeoff power would shake aircraft and I was concerned the passenger would be less comfortable and more anxious). Constant takeoff torque test was satisfactory. Maintenance control indicated the problem was fixed (frequently relays or other electrical components reset themselves when recycling electrical power, common first course of action). I asked for job control number for the discrepancy I was about to enter in aircraft logbook. Maintenance control told me that no logbook entry was required and no 'corrective action' entry was required. I disagreed and asked to speak with our dispatcher. Dispatch had been listening to our conversation and agreed that no entry was required. Again I disagreed and asked for a flight manager. Dispatch told me he would contact the flight manager on call. A reasonable amount of time elapsed for dispatch to contact and explain the reason I asked for a third opinion. Dispatch said the flight manager said no entry required, you're good to go. Discussions with the first officer were continued as to whether we actually still needed a logbook discrepancy and corrective action since we followed this course of action and no written procedure addressed this issue. If the flight manager on duty ok's it then we must be good to go -- we thought. Second takeoff attempt (without a logbook entry) resulted in an abort for same reason (would not produce selected power). We taxied back to gate area holding on ramp where we could do more troubleshooting for maintenance if required. Maintenance controller notified of second abort and the item was deferred per MEL procedures (which includes a logbook entry discrepancy and correction action). Third takeoff attempt was successful and flight to destination (dtw) was normal.

Title: A COMMERCIAL FIXED WING LTT ACFT AFTER REJECTING A TKOF DUE TO BOTH ENGS NOT MAKING TKOF PWR AS SELECTED ON THE CONSTANT TKOF TORQUE SYS AND THEN CHKING THE SYS OK THE CREW HAD DISCUSSIONS WITH MAINT AND DISPATCH ON LOGBOOK ENTRIES.
Narrative: ABORTED TKOF AFTER BOTH ENGS WOULD NOT PRODUCE PWR SELECTED ON CONSTANT TKOF TORQUE. TAXIED OFF RWY 25 AND STOPPED ON TXWY TO EVALUATE PERTINENT SWITCH POS AND NOTIFY MAINT CTL BY RADIO. UNDER SUPERVISION OF MAINT CTL, I RECYCLED ELECTRICAL PWR TO ACFT AND TESTED CONSTANT TKOF TORQUE (STATICALLY) ON TXWY WITH A REDUCED PWR SETTING (REDUCED BECAUSE FULL TKOF PWR WOULD SHAKE ACFT AND I WAS CONCERNED THE PAX WOULD BE LESS COMFORTABLE AND MORE ANXIOUS). CONSTANT TKOF TORQUE TEST WAS SATISFACTORY. MAINT CTL INDICATED THE PROB WAS FIXED (FREQUENTLY RELAYS OR OTHER ELECTRICAL COMPONENTS RESET THEMSELVES WHEN RECYCLING ELECTRICAL PWR, COMMON FIRST COURSE OF ACTION). I ASKED FOR JOB CTL NUMBER FOR THE DISCREPANCY I WAS ABOUT TO ENTER IN ACFT LOGBOOK. MAINT CTL TOLD ME THAT NO LOGBOOK ENTRY WAS REQUIRED AND NO 'CORRECTIVE ACTION' ENTRY WAS REQUIRED. I DISAGREED AND ASKED TO SPEAK WITH OUR DISPATCHER. DISPATCH HAD BEEN LISTENING TO OUR CONVERSATION AND AGREED THAT NO ENTRY WAS REQUIRED. AGAIN I DISAGREED AND ASKED FOR A FLT MGR. DISPATCH TOLD ME HE WOULD CONTACT THE FLT MGR ON CALL. A REASONABLE AMOUNT OF TIME ELAPSED FOR DISPATCH TO CONTACT AND EXPLAIN THE REASON I ASKED FOR A THIRD OPINION. DISPATCH SAID THE FLT MGR SAID NO ENTRY REQUIRED, YOU'RE GOOD TO GO. DISCUSSIONS WITH THE FO WERE CONTINUED AS TO WHETHER WE ACTUALLY STILL NEEDED A LOGBOOK DISCREPANCY AND CORRECTIVE ACTION SINCE WE FOLLOWED THIS COURSE OF ACTION AND NO WRITTEN PROC ADDRESSED THIS ISSUE. IF THE FLT MGR ON DUTY OK'S IT THEN WE MUST BE GOOD TO GO -- WE THOUGHT. SECOND TKOF ATTEMPT (WITHOUT A LOGBOOK ENTRY) RESULTED IN AN ABORT FOR SAME REASON (WOULD NOT PRODUCE SELECTED PWR). WE TAXIED BACK TO GATE AREA HOLDING ON RAMP WHERE WE COULD DO MORE TROUBLESHOOTING FOR MAINT IF REQUIRED. MAINT CTLR NOTIFIED OF SECOND ABORT AND THE ITEM WAS DEFERRED PER MEL PROCS (WHICH INCLUDES A LOGBOOK ENTRY DISCREPANCY AND CORRECTION ACTION). THIRD TKOF ATTEMPT WAS SUCCESSFUL AND FLT TO DEST (DTW) WAS NORMAL.
